Not the same definition as a scanner. A scanner can provide much better

Sometimes a simple eye inspection cannot identify clearly the watermarks
A scanner can be used as a microscope with my higher resolution than a
digital camera or a samrt phone. Digital cameras/ smartphones are like
more sophisticated replacement of human eye but not so perfect as a
scanner.

I normally prefer a scanner, too, but a digital camera with a macro mode
that lets you take a picture just a few inches away from the stamp works
well. You may need a stand for the camera and some supplementary
lighting to get the best possible picture. You can zoom a digital photo
as well as a stamp image.
